Behavioral and electrophysiological evidence of species-specific face processing

Several recent reports suggest that the behavioral and cortical specificity of face processing may be influenced by experience. To test this hypothesis, behavioral and electrophysiological data were recorded from adults in response to human and monkey faces differing in familiarity and orientation. An analysis of event-related potential and behavioral data revealed differentiation across species, familiarity, and orientation. Behavioral measures were correlated with amplitude and latency measures for each factor of interest. These analyses revealed that accuracy was positively related to the amplitude of the vertex positive potential in the human face task but not in the monkey face task. These findings suggest that previous experience with different categories of faces modulates the link between behavioral and electrophysiological measures of face processing.     

Managers' variance investigation decisions: an experimental examination of probabilistic and outcome ambiguity

Information ambiguity is prevalent in organizations and may influence management decisions. This study examines, given imprecise probabilities or outcomes, how managers decide which department's performance to investigate further when they are provided with performance benchmarks expressed in numerical intervals. Seventy‐nine MBA students participated in two experiments involving investigation decisions. We presented participants with interval benchmarks of a firm's expenses. Being below or above the benchmark should have been seen as equally negative. We found that, when facing outcome ambiguity, our participants consistently preferred to investigate further those departments whose performance was described as having an ambiguous outcome (when the outcome's range was centered either below or above the interval benchmark). However, when facing probabilistic ambiguity, there were two predominant choice patterns: consistently choosing to investigate the department whose performance is described with an ambiguous probability, or consistently choosing to investigate the department with unambiguous performance. To gain further insight, we conducted a follow‐up study collecting written protocols of participants' reasons for making choices involving ambiguous performance information. The results show that our participants displayed similar decision‐making processes when facing outcome ambiguity and probabilistic ambiguity. Copyright © 2001 John Wiley & Sons, Ltd.     

The Hippocratic Oath as Epideictic Rhetoric: Reanimating Medicine's Past for Its Future

As an example of Aristotle's genre of epideictic, or ceremonial rhetoric, the Hippocratic Oath has the capacity to persuade its self-addressing audience to appreciate the value of the medical profession by lending an element of stability to the shifting ethos of health care. However, the values it celebrates do not accurately capture communally shared norms about contemporary medical practice. Its multiple and sometimes conflicting versions, anachronistic references, and injunctions that resist translation into specific conduct diminish its longer-term persuasive force. Only when expunged of these elements and reconstructed using values over which there is widespread agreement can the Oath succeed in moving its audience from core values located in past discussions to principled action in the future.     

Workload and burnout in nurses

This paper examines the relationship between workload, burnout and somatization in nurses. The respondents consisted of 1363 nurses employed in hospitals, which were undergoing extensive restructuring. Results of structural equation analyses showed that workload was positively related to emotional exhaustion. Emotional exhaustion led to cynicism and somatization, and cynicism was negatively related to nurses' professional efficacy. Implications of the results for nursing practice are discussed.

Ability in perceiving nonnative contrasts: Performance on natural and synthetic speech stimuli

The perception of the distinction between /r/ and /l/ by native speakers of American English and of Japanese was studied using natural and synthetic speech. The American subjects were all nearly perfect at recognizing the natural speech sounds, whereas there was substantial variation among the Japanese subjects in their accuracy of recognizing /r/ and /l/ except in syllable-final position. A logit model, which additively combined the acoustic information conveyed byF1-transition duration and byF3-onset frequency, provided a good fit to the perception of synthetic /r/ and /l/ by the American subjects. There was substantial variation among the Japanese subjects in whether theF1 andF3 cues had a significant effect on their classifications of the synthetic speech. This variation was related to variation in accuracy of recognizing natural /r/ and /l/, such that greater use of both theF1 cue and theF3 cue in classifying the synthetic speech sounds was positively related to accuracy in recognizing the natural sounds. However, multiple regression showed that use of theF1 cue did not account for significant variance in natural speech performance beyond that accounted for by theF3 cue, indicating that theF3 cue is more important than theF1 cue for Japanese speakers learning English. The relation between performance on natural and synthetic speech also provides external validation of the logit model by showing that it predicts performance outside of the domain of data to which it was fit.     

Correlates of Fear of Falling in Older Adults Who Have Experienced a Fall

Nearly one half of older adults who have experienced a fall report a fear of falling. The present study examined several variables in relation to fear of falling. Thirty community-dwelling older adults, over 60 years of age, who experienced a fall in the previous 12 months participated. Subjects were divided into two groups (low-fear and high-fear) and compared on scores on a Fear of Falling questionnaire, the Falls Efficacy Scale, the Philadelphia Geriatric Center Pain Intensity Scale, the Ways of Coping Checklist-Revised, the Geriatric Depression Scale-15, and the State–Trait Anxiety Inventory for Children. At least a little fear of falling was reported by 25 (83.3%) of the individuals who had fallen. Highly fearful fallers were significantly more likely to endorse higher levels of pain and general anxiety than fallers reporting low levels of fear of falling. Future directions for research were noted.     

Regional variation of cloze probabilities for sentence contexts

In 1980, Bloom and Fischler published a paper describing a set of sentence contexts (SCs) and their cloze probabilities (CPs). This material has subsequently been employed in numerous studies of linguistic processing. We sought to define the completion words and their CPs for Bloom and Fischler’s sentences in an inner-city British population in order to establish reliable norms for subsequent studies in the U.K. One hundred and fifty incomplete SCs were presented to 73 volunteers. The CPs for each of the words used to complete the SCs were computed. We then compared the CPs from our sample with those from Bloom and Fischler. There were significant differences between CPs from each sample in 14% of the SCs analyzed (p < .01). Our data suggest that studies employing SCs and CPs may require locally defined norms if the test population differs substantially from the original one. The consequences of employing SCs and CPs to study linguistic processing without normalization are discussed.     

The Relationship of Antifat Attitudes to Other Prejudicial and Gender‐Related Attitudes1

Overweight people in society face a number of obstacles. Negative attitudes toward overweight people contribute to this experience. This study examined the relationship of antifat attitudes to other prejudicial attitudes (e.g., racism, sexism, homophobia) and gender‐related attitudes. A total of 179 undergraduate participants completed measures of prejudicial attitudes, including antifat attitudes. Multiple regression analyses revealed that a combination of demographic and attitudinal variables predicted antifat attitudes. Antifat attitudes are stronger for men, Caucasians, and gender‐typed individuals; compared to women, African Americans, and androgynous individuals, respectively. After controlling for demographics, weight‐related variables, and social desirability, gender‐role egalitarianism, racism, and homophobia significantly correlated with antifat attitudes. The implications and limitations of this study are discussed regarding the importance of research in antifat and other prejudical attitudes.     

Self-construal and the processing of covariation information in causal reasoning

Causal induction provides a nice test domain for examining the influence of individual-difference factors on cognition. The phenomena of both conditionalization and discounting reflect attention to multiple potential causes when people infer what caused an effect. We explored the hypothesis that individuals with an independent self-construal are relatively less sensitive to context (other causes) than are individuals with an interdependent self-construal in this domain. We found greater levels of conditionalization and data consistent with discounting for participants in whom we primed an interdependent self-construal than for participants in whom we primed an independent self-construal.
